My old Vista box still browses just fine.

IPv4 hasn't changed in a long time.

You should still be able to browse the web. If you're getting errors, its probably due to an outdated web browser.

It’s screws up reading some pages, but still works 95% of the time for me.

They are not specifically blocked. But that doesn't mean they'll continue to work either.

For one example, I have a first-generation iPad. And it still "connects" just fine to the Internet. I can browse (most) web pages and even check my email.

But if I fire up the Hulu application it complains and won't connect. And there's not a new version of the Hulu app that will run on my old old iPad.

Fortunately the old Netflix app still works

So my computer isn't "blocked" but it's not able to connect to all of the services that used to work.

I have an office in the basement. I had an old Dell tower, which stopped connecting to the wireless network and going online. I switched it out with a newer old Dell tower, used the same cables. It connected to the wireless Internet. I saw a message in January that it would stop being supported 1/20/20. Upstairs, I am currently using an older Dell laptop that says the browser isn't supported, but it connects okay. I had my tablet downstairs yesterday and it had a good wireless Internet connection in my office. I tried a few things, but couldn't get the tower to connect.

I had it on a couple weeks ago, and it connected. There was a long list of wireless networks then, but when I turned it on last week, that list was gone. I think there was an update a couple weeks ago.

I think it might be the update, read that sometimes they can cause connection problems. It doesn't seem like it would be the cables, because the laptop I switched out worked for over 2 months when I used it. I'm spending the next few days getting a new laptop set up, and other tech chores. Happy Leap Day!

I had the wifi go bad on my motherboard I got a $10 USB wifi on newegg and was good to go again.
